The fact is that the system services you use to access a RTDM devices are special services handled by Xenomai RTM skin, they are not usual Linux services. So, there is no way you can access an RTDM device node with Linux system calls (which is what echo 1 > /dev/gpio1 does). Please avoid replying a random thread to post your question, as it messes up those of us who order mails by threads, and notably the mailing list archives. -- Gilles.
